Types of Float Switches

We have different types of float switches suitable for level control and system automation in a variety of mediums, including ATEX-approved low-current microswitch models for Zone 0 applications, floats with EPR insulated cables for fuel applications and models constructed from WRAS approved materials for safe installation in potable water sources.

How to Install a Float Switch

Float switches can be installed in a number of ways depending on the application – they can be used for filling and emptying or alarm applications.

For installation into tanks and sumps (such as in pumping stations, water treatment plants and basements), float switches need to be tethered to the inside of the tank or on the pump in a place where it can move freely to activate and be easily accessed for visual inspections and maintenance.

  • Filling and low-level alarm usage – use the brown and blue cable cores on the FLO Series float switch, this means the contact will close when the float is down and open when it is up.
  • Emptying and high-level alarm usage – use the brown and black cable cores on the FLO Series float switch, this means the contact will open when the float is down and close when it is up.
  • Independent alarm operation (low, mid and high level) – separate float switches are needed for each alarm that is required.

Common Float Switch Issues

Common issues encountered by pump float switches include a lack of free movement if the float is not correctly positioned, loose mounting causing the float to move from its fixed position and obscure level monitoring or premature failure due to degradation from using an incorrectly selected float for the application.

These issues can all be avoided with correct float switch selection and installation, contact our team for expert support with your level control unit today.
